Hereinafter, an RRC state and an RRC connection method of the electronic device 201 will be described. In an embodiment, the RRC state indicates whether or not the RRC of the electronic device 201 is logically connected to the RRC of the base station. may be referred to as an RRC idle state (RRC_IDLE). According to an embodiment, handover is a technique for managing mobility of the electronic device 201 in a connected state (eg, RRC-CONNECTED), and cell reselection is an electronic device in an idle state (eg, RRC-IDLE). (201) may represent a technique for managing the mobility. While the base station determines which cell the electronic device 201 will handover to during handover, the electronic device 201 may determine which cell to select when the electronic device 201 reselects a cell. For example, when the electronic device 201 camps on a cell during cell reselection (eg, after the electronic device 201 completes a cell reselection operation, the electronic device 201 transmits system information and paging information from the newly selected cell). You can decide whether to stay or stay.

According to an embodiment, the base station may identify the electronic device 201 in the RRC connection state in units of cells. On the other hand, the base station cannot identify the electronic device 201 in the RRC idle state in a cell unit, and may manage it in a tracking area (TA) unit, which is a larger area unit than the cell. For example, in order for the electronic device 201 in the RRC idle state to receive a service such as voice or data from a cell, it must make a state transition to the RRC connected state.

According to an embodiment, when the electronic device 201 is powered on by a user, the electronic device 201 may first search for an appropriate cell (eg, a cell selection operation) and then exist in the RRC idle state in the corresponding cell. When it is necessary to establish an RRC connection in an RRC idle state, the electronic device 201 may perform an RRC connection establishment operation with an RRC of a base station to transition to an RRC connection state. In an embodiment, when establishing an RRC connection, for example, uplink data transmission is required for reasons such as a user's call attempt, or a paging message is received from the base station and a response message is generated. It may include a case where it is necessary to transmit .

According to an embodiment, the base station may not have information (context) of the electronic device 201 when the electronic device 201 exists in an idle state. Accordingly, when the electronic device 201 is in the idle state, the electronic device 201 may perform a mobility-related operation such as a cell selection or a cell reselection operation without receiving a command from the base station. According to an embodiment, the electronic device 201 in the idle state may periodically wake-up and check whether there is a paging message for searching for the electronic device 201 . While camped on a cell, the electronic device 201 receives system information broadcast by a base station, periodically measures a signal of a serving cell, and when cell reselection is triggered, An operation such as reselecting a serving cell by measuring a signal may be performed.

Hereinafter, an operation example of the electronic device 201 according to various embodiments will be described with reference to FIG. 4 .

4 is a diagram illustrating an operation of providing a communication service of the electronic device 201 according to various embodiments of the present disclosure. 5 and 6 show a paging period (or paging position) (eg, read paging) corresponding to a plurality of subscriber identification modules (eg, the first SIM 410 and the second SIM 420 ) according to various embodiments of the present disclosure; It is a drawing showing an example of (time to be confirmed).

In an embodiment, the operation illustrated in FIG. 4 may be an operation performed by a processor (eg, the processor 120 of FIG. 1 ) of the electronic device 201 , and the electronic device 201 performs two subscriber identification modules. (eg, the first SIM, the second SIM) may be an example of operation.

As shown in FIG. 4 , in FIG. 4 , a scheduler, an air interface protocol corresponding to the first SIM 410 (eg, an RRC layer 411 , a PHY layer 413 ), and a second SIM 420 ) A portion of the corresponding air interface protocol (eg, RRC layer 421, PHY layer 423) is shown.

In various embodiments, the electronic device 201 operates in an idle mode without data transmission/reception through, for example, the first SIM 410 and the second SIM 420 (eg, the idle state). and paging (or paging information) may be monitored. For example, the electronic device 201 currently exists in an idle state and camps at a first base station 203 corresponding to the first SIM 410 and a second base station 205 corresponding to the second SIM 420 . It may be in a state in which it is on (camp on).

According to an embodiment, the electronic device 201 may receive system information from a base station (eg, the first base station 203 of FIG. 2 and the second base station 205 of FIG. 2 ) in the idle mode. According to an embodiment, in FIG. 4 , a first paging service is requested (eg, first paging) from the first base station 203 in which the electronic device 201 is camped on by the first SIM 410 in the idle mode. message is received), and thereafter, a request for a second paging service (eg, reception of a second paging message) may be generated from the second base station 205 camped on by the second SIM 420 . In one embodiment, although the first base station 203 and the second base station 205 are described for convenience of description, the present invention is not limited thereto. For example, the electronic device 201 may use the first SIM 410 and the second SIM 420 based on different cells (eg, the first cell and the second cell) included in one or each of the base stations. It may also be understood as operating in units of cells.

Referring to FIG. 4 , in operation 401 , according to an embodiment, when a paging (or packet service request) occurs from a base station currently camped on (eg, the first base station 203 ), the electronic device 201 , A request (eg, PCH_CONFIG_REQ) for forming a paging channel (PCH) for transmitting a paging message to the PHY layer 413 through the RRC layer 411 may be transmitted to the PHY layer 413 .

According to an embodiment, in operation 403 , the PHY layer 413 may transmit a resource allocation request (eg, RESOURCE_REQ) to the scheduler 430 in response to PCH_CONFIG_REQ.

According to an embodiment, when paging occurs based on the first SIM 410 , operation 405 (eg, PCH_CONFIG_REQ for the second paging message) and operation 407 (eg, for the second paging message) RESOURCE_REQ), paging may also occur based on the second SIM 420 . For example, a case may occur in which paging time points overlap in the first SIM 410 and the second SIM 420 . In this way, when the paging time points of the first SIM 410 and the second SIM 420 overlap, one paging may not be received and the paging reception probability may decrease. This will be looked at with reference to FIG. 5 .

Referring to FIG. 5 , according to an embodiment, in relation to the first SIM 410 , the electronic device 201 has a first paging period (or paging location) 510 of the first SIM 410 (eg: Paging related to the first SIM 410 by waking up at a time to read (or check) paging, for example, every paging discontinuous reception (DRX) cycle (eg, time points t1, t3 and t5) You can check (or monitor) for messages. According to an embodiment, in relation to the second SIM 420 , the electronic device 201 wakes up at every second paging cycle 520 (eg, time t1 to t5 ) of the second SIM 420 to perform the first 2 It can be checked whether there is a paging message related to the SIM 420 . In this case, the timing of checking the paging related to the first SIM 410 in the first paging cycle 510 and the timing of checking the paging related to the second SIM 420 in the second paging cycle 520 overlap at least partially This may cause a paging conflict.

According to an embodiment, in FIGS. 5 and 6 , the time interval T1 between paging times of the first paging period 510 is set longer than the time interval T2 between paging times of the second paging period 520 . can indicate For example, it may represent a case in which the paging time of the second paging period 520 occurs more frequently than the paging time of the first paging period 510 .

In general, the electronic device 201, for example, when a paging collision occurs (eg, time t1, t3, t5), the first paging (or wake-up SIM (eg, the first SIM 410 ) )), it is possible to perform a paging-related operation (eg, reception of a paging message related to the first SIM 410) (eg, grant), and to perform paging (or wake-up) that occurs later For the SIM (eg, the second SIM 420 ), a paging-related operation (eg, reception of a paging message related to the second SIM 420 ) may not be performed (eg, reject). Conventionally, it may not be possible to receive a paging related to the second SIM 420. For example, when the paging time points of the first SIM 410 and the second SIM 420 overlap, the paging related to one SIM is received. probability may be lowered.

Referring back to FIG. 4 , the scheduler 430 relates to paging of the first SIM 410 and the second SIM 420 according to the scheduling according to the paging cycle of the first SIM 410 and the second SIM 420 . action can be determined. According to an embodiment, the scheduler 430 may determine to perform a paging-related operation on the first SIM 410 and not perform a paging-related operation on the second SIM 420 . Accordingly, the scheduler 430 transmits, in operation 409 , an acknowledgment response (eg, GRANT) to the PHY layer 413 of the first SIM 410 , and in operation 411 , the second SIM 420 . A rejection response (eg, REJECT) may be delivered to the PHY layer 423 of the . According to an embodiment, when transmitting a rejection response to the PHY layer, the scheduler 430 may include or separately provide a rejection cause (eg, paging collision information). According to an embodiment, the rejection response may be delivered to the PHY layer as a PCH.

According to an embodiment, the PHY layer 413 to which the acknowledgment response (eg, GRANT) is transmitted may perform a paging-related operation through the RRC layer 411 . For example, in relation to the first SIM 410 , in an RRC idle state, the electronic device 201 receives an RRC packet service such as voice or data from a base station (eg, a camped-on cell). A state transition may be made to an RRC connected state.

According to an embodiment, the PHY layer 423 to which the rejection response (eg, REJECT) is transmitted, in operation 413 , in response to the rejection response of the scheduler 430 , provides the RRC layer 421 with collision information (eg, : COMPLICT_IND) can be transmitted.

According to an embodiment, in operation 415 , the RRC layer 421 executes a timer (eg, a timer start) in response to the collision information (eg, COMPLICT_IND) of the PHY layer 423 . )can do. According to an embodiment, the RRC layer 421 may count a predetermined time related to cell reselection.

According to an embodiment, the RRC layer 421 transmits a collision response (eg, COMPLICT_RSP) to the PHY layer 423 in operation 417 in response to a timer expired (eg, a predetermined time expires). and, in operation 419 , an operation related to cell reselection may be initiated (cell reselection triggering). In various embodiments, the electronic device 201 may perform a cell reselection operation related to the second SIM 520 based on system information broadcast by the base station.

In various embodiments, when a paging collision occurs between the first SIM 410 and the second SIM 420 , the collision does not occur with respect to the second SIM 420 in which paging is rejected (or RRC idle). A cell reselection operation for selecting a non-existent cell may be performed. Through this, in various embodiments, the paging reception rate of the electronic device 201 may be increased by avoiding a paging collision between the first SIM 410 and the second SIM 420 . An example of this is shown in FIG. 6 . A cell reselection operation according to various embodiments will be described with reference to the drawings to be described later.

According to an embodiment, after the cell reselection operation is completed, the electronic device 201 may receive system information and paging information from the newly selected cell, and based on the received paging information, a paging cycle ( Example: A third paging period 530) may be set. For example, referring to FIG. 6 , in relation to the second SIM 420 , the second paging cycle 520 of FIG. 5 is a first related to a cell newly selected by cell reselection (eg, camp-on-cell). It may be changed to 3 paging periods 530 . According to an embodiment, the first paging period 510 may include, for example, time points t1, t3, and t5, and the third paging period 530 does not overlap with the first paging period 510. , for example, may include time points t11 to t16. In this way, the paging section for paging monitoring related to the first SIM 410 in the first paging period 510 overlaps the paging section for paging monitoring related to the second SIM 420 in the third paging cycle 530 . Therefore, a paging conflict may not occur.

For example, the processor 710 may exclude Cell B from a target cell in the cell reselection operation of the second SIM 750 .

According to various embodiments, the processor 710 selects a target cell for a serving cell during the cell reselection operation of the second SIM 750 in the idle state, not only the signal strength (eg, RSRP) but also the signal quality (eg, RSRQ, reference signal received quality) may be additionally considered. According to an embodiment, the processor 710 selects a cell that satisfies a criterion (eg, a reference level) in which a cell reception level (eg, signal strength) is set as a target cell (eg, a candidate for a serving cell) during cell reselection. cell) can be selected. For example, the reference level may include a signal measurement value for normally exchanging a signal (or message) between the electronic device 201 and a cell. According to an embodiment, if cell reselection is performed with a weak electric field cell during cell reselection, a paging reception rate may decrease. Accordingly, according to various embodiments, the electric field condition may be set as the target cell condition by considering the electric field condition to be at least higher than the value specified in the 3GPP standard.
